0007182: To limit or switch off sound, when few MIDI notes are selected

Description

Ardour has a useful possibility to sound selected MIDI notes. This mode can be activated here:

Preferences>MIDI>MIDI Preferences>

"Sound MIDI notes as they are selected in the editor".

This mode works fine with single notes, but when we select several notes - they sound together (volume level summary!). If, for example, we have about 20 notes in a region and press Ctrl+A (to select all of them) - it produces an impermissible level of sound.
The proposal is:
-to make a level limitation for several notes sounding;
-or to switch off the sounding of the selected group of notes at all;
-or to sound the first note of the selected note group.
